Question

When 0.1625 g of magnesium is burned in a bomb calorimeter that has a heat capacity of 3.03 kJ/ ∘

C, the temperature increases by 1.252 ∘
C. How much heat (kJ/mol) is liberated during the burning of the magnesium?

Answer 1

Answer: Heat released during the burning of 0.1625 g of magnesium is 3.79356 kilo Joules.

Step-by-step explanation:

Mass of the magnesium : 0.1625 g

Heat capacity of the bomb calorie-meter,C = 3.03 kJ/°C

Change or increase in temperature
`\Delta T`= 1.252°C

Heat =
`C* \Delta T=3.03 kJ/^oC* 1.252^oC=3.79356 kJ`

Heat released during the burning of 0.1625 g of magnesium is 3.79356 kilo Joules.
